Source Driven Development grounds every framework-specific implementation decision in official documentation, so code is verifiable and follows current best practices. Use it when building with any framework or library where correctness matters, or when you want source-cited code free from outdated patterns.

Test-Driven Development guides writing a failing test before code to make it pass. Use it when implementing logic, fixing bugs, or modifying behavior to prove code works.

API and Interface Design guides the creation of stable, well-documented interfaces including REST APIs, GraphQL schemas, module boundaries, and component props. Use it when designing new endpoints, defining contracts between teams, or changing existing public interfaces.

Browser Testing runs tests and inspections in a real browser via Chrome DevTools MCP. Use it when building or debugging browser UI to inspect the DOM, capture console errors, analyze network requests, profile performance, or verify visual output.

Code Review and Quality conducts multi-axis code review across correctness, readability, architecture, security, and performance before merging changes. Use it to assess code quality before code enters the main branch.

Code Simplification simplifies code by reducing complexity while preserving exact behavior. Use it when refactoring for clarity, improving readability, or reviewing code that has accumulated unnecessary complexity.

Design Critique runs a 5-dimension expert design review on any HTML artifact, scoring Philosophy, Visual hierarchy, Detail, Functionality, and Innovation from 0–10. It outputs a self-contained HTML report with a radar chart, evidence-backed scores, and Keep / Fix / Quick-wins lists for design reviews, audits, or critiques.

Understand Diff analyzes git diffs or pull requests against a project knowledge graph to identify changed components, affected dependencies, and architectural layers. It then provides a risk assessment and writes a diff overlay for the understand dashboard.

Code Simplifier reviews Rust code for idiomatic simplification patterns, reducing over-engineering and unnecessary allocations without changing behavior. Use it to apply Rust idioms like iterator chains, early returns, and Option/Result chaining while respecting project constraints.

Performance analyzes RTK CLI startup time, memory usage, and token savings to detect and fix performance regressions. Use it after filter changes, dependency additions, or before release to verify the CLI meets <10ms startup, <5MB memory, and 60-90% token savings targets.

PR Review batches open pull requests in order of complexity, checks merge readiness (conflicts, CLA, reviews), reads diffs, and asks for explicit approval before merging. It also posts comments on blocked PRs.

PR Triage audits open pull requests, flags risks, and helps choose which PRs need deeper review. It can draft and post review comments, with language handling for French or English.
